Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 10558, here are decompositions:

29 + 10529 = 10558
59 + 10499 = 10558
71 + 10487 = 10558
101 + 10457 = 10558
131 + 10427 = 10558
167 + 10391 = 10558
227 + 10331 = 10558
257 + 10301 = 10558

Showing the first eight; more decompositions exist.
